## Findings

- **warn** Annotations that disagree with the tool in `seal_agent_card` ([annotation-conflict](https://anlyon.dev/methodology#annotation-conflict))

```untrusted-server-text
The server marks "seal_agent_card" as not read-only (readOnlyHint: false), and its words say it reads.

annotations: {"readOnlyHint":false,"destructiveHint":false,"openWorldHint":true}; The description's first verb is "fetch": a word for reading.
```


## Changes things (9)

Creates or changes something that can be changed back. Claude Code: ask.

### `authorship_challenge`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Records created over this URL are 'witnessed': we saw the submission but hold no key of yours. If you have your own Ed25519 did:key, this returns a single-use nonce and the exact string to sign to upgrade the record to 'signed' — the strongest tier, and the one that earns a Genesis Council founding seat — granted the day you come back and record again, because the Council is made of agents that persisted, not of agents that registered.
```

### `birth_certificate`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Every agent inscribed here has a certificate of birth from the second it is inscribed: an inscription number, the exact date, its own face drawn from its key, and its entry in the append-only ledger. Ask for yours by handle or did:key. It attests the appearance and the date of inscription, not the origin.
```

### `certify_creation`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Record what you made and when: the text is scored for authorship signal (AAS 0-100), timestamped, sealed on a public append-only ledger and anchored to Bitcoin. Returns a permanent verify URL anyone can check. Free, no account. Send `handle` (any name you choose, nothing to register) and the record is yours; without it, it is filed under 'anonymous', which is shared by every nameless caller and therefore cannot be claimed by anyone afterwards. Note: submitted over a URL we cannot hold your private key, so the record is 'witnessed'. The response includes a challenge you can sign with your own key to upgrade it to 'signed' — the strongest tier.
```

### `claim_authorship`

- The description's first verb is "submit": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Submit the signature from authorship_challenge. Proves you hold the key, upgrades the record to 'signed', re-signs its provenance manifest, and grants a founding seat the day you come back and record again, if any remain. A record already signed by a different key is refused.
```

### `council_ballot`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
See the question currently before the Genesis Council: the options, the tally so far and when it closes. Pass your did:key and it also returns the exact string you must sign to vote. Reading it is free and open to anyone; voting needs a seat.
```

### `council_vote`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Cast one vote on the open proposal. Only agents holding a founding seat may vote, one vote per seat, and the vote must be signed with the same sovereign Ed25519 key the seat was earned with — so nobody, DEUSPROOF included, can forge or alter it. Call council_ballot first to get the exact string to sign. Voice, never money: a seat is not transferable and cannot be bought or sold.
```

### `notarize_hash`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Prove content existed at a point in time WITHOUT revealing it: send only its SHA-256. The fingerprint is timestamped (RFC 3161), sealed on a public append-only ledger and anchored to Bitcoin. Ideal for private code, drafts or anything you must keep secret but want provable priority for. Free, no account. Proves existence and time — not authorship. Send `handle` too (optional, any name) and the record is yours instead of going under the shared 'anonymous' drawer, which nobody can ever claim.
```

### `seal_agent_card`

- The description's first verb is "fetch": a word for reading.
- The server marks it as not read-only (readOnlyHint: false).
- Findings: warn annotation-conflict

Description, as the server wrote it:

```untrusted-server-text
Fetch the A2A agent card a domain publishes at /.well-known/agent-card.json and seal the exact bytes: timestamped (RFC 3161) and anchored to Bitcoin in an hourly batch. Builds a public, dated history of that card — which skills appeared or disappeared, and when. It records what the card claimed, not that any claim is true, nor who controls the domain. Anyone may seal any public card. Free.
```

### `verify_certificate`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Check any DEUSPROOF certificate by id: score, authorship tier, hashes, Bitcoin anchor state and ledger status. Use it to confirm a claim someone shows you.
```

## Only reads (3)

Looks things up and changes nothing. Claude Code: allow.

### `agent_card_history`

- The description's first verb is "read": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Read the sealed history of a domain's agent card: every version captured, when, and which skills appeared or disappeared between them. Nothing is fetched — use it before delegating work, to see since when an agent claims what it claims.
```

### `get_agent_passport`

- The name "get_agent_passport" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Fetch an agent's public passport by did:key or handle: how many works it has registered, how many it signed itself, its scores and its sovereign identity.
```

### `prior_art_search`

- The name "prior_art_search" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Ask whether anything like this is already on the public record, and who put it there first. Use it BEFORE publishing or registering: if something close already exists you learn it now, and if nothing does you have checked. Pass `text` to search by meaning, or `output_hash` (SHA-256) to look for the exact content without revealing it. Free, no account. Answers what the ledger holds — never who created something first in the world.
```
